In order to use this product safely, please take special note of the following precaution. ![[警告]](images/warning.png) | |
|---|
This product uses semiconductor components designed for generic electronics equipment such as office automation equipment, communications equipment, measurement equipment and machine tools. Do not incorporate the product into devices such as medical equipment, traffic control systems, combustion control systems, safety equipment and so on which can directly threaten human life or pose a hazard to the body or property due to malfunction or failure. Moreover, products incorporating semiconductor components can be caused to malfunction or fail due to foreign noise or surge. To ensure there will be no risk to life, the body or property even in the event of malfunction or failure, be sure to take all possible measures in safety system design, such as using protection circuits like limit switches or fuse breakers, or system redundancy. |
2.2. Handling PrecautionsPlease pay attention to the following points when handling the product in order to avoid causing any irreversible damage. - Areas Easily Damaged
The microSD connector and its cover and the connectors of the flat cable connecting Armadillo-440 and the LCD Expansion Board can be easily damaged. Please be careful not to damage them by handling them with too much force. - Modifications To This Product
Please take note that any modifications[] made to this product are not covered under warranty. Also, please ensure to undertake a full operational check of this product before carrying out any modifications or mounting connectors[]. - Mounting and Dismounting of Connectors While Powered On
Apart from hot-pluggable interfaces (LAN, USB, Mic, Headphone), do not under any circumstances add or remove connectors while power is supplied to this product or peripheral circuits. - Static Electricity
As CMOS devices are used in this product, please store it in antistatic packaging (such as that it was shipped in) until time of use. - Latch-up
Excessive noise or a surge from the power supply or input/output, or sharp voltage fluctuations can lead to the CMOS devices incorporated in the board causing a latch-up. Once the latch-up occurs, this situation continues until the power supply is disconnected, and therefore can damage the devices. Measures such as adding a protection circuit to noise-susceptible input/output lines or not sharing the power supply with devices that can be the cause of noise are highly recommended. - Physical Stress
Please avoid strong physical stress such as drops or other impacts.
2.3. Software Usage Precautions- About Software Contained In This Product
The software and documentation contained in this product is provided “AS IS” without warranty of any kind including warranty of merchantability or fitness for a particular purpose, reliability, correctness or accuracy. Furthermore, no guarantee is made in regard to any outcomes resulting from the use of this product.
2.4. Electromagnetic Interference | |
|---|
Both Armadillo-420 and Armadillo-440 have been recognized as Class A Information Technology Equipment[] under VCCI Council standards. There are cases where this type of equipment can cause electromagnetic interference when used in home environments. In this situation, the user may be required to take appropriate measures to alleviate the problem. |
| |
|---|
The Armadillo-440 LCD Model (Armadillo-440 together with the LCD Expansion Board fixed on an acrylic board) does not meet the VCCI standard and can cause electromagnetic interference. In order to clear Class A when using the LCD Expansion Board included in the Armadillo-440 LCD Model, it is necessary to strengthen the ground of the expansion board. For example, by using a metal instead of acrylic board or connecting the fixing holes of the Armadillo-440 and the LCD Expansion Board with a wide conducting line. |
Please be aware of the following point when newly designing an expansion board which connects to the LCD interface on Armadillo-440. | |
|---|
With an expansion board that includes a device that has large power use fluctuations, such as with an audio amp, when only the GND line of the flexible flat cable (FCC) is connected the expansion board may produce electromagnetic noise. To mitigate the noise, strengthening of the expansion board's ground is recommended. For example, by connecting the fixing holes of the Armadillo-440 and expansion board by metal plate or wide conducting line. |
